It was also surprising to detect HPV-12 genotype in one specimen, because in the majority of studies, it was not mentioned to infect buccal mucosa [ 9, 21] and is rather considered to be etiologically significant in cutaneous epidermodysplasia verruciformis (EV -associated HPV (EV -associated
If you (the research team) come within one hour (of death), you can't collect the specimens because then everyone in the house will be crying and mourning.
While studies have validated the use of this type of specimen by showing agreement between results from archived and fresh specimens from the same women (27 ), concerns exist that the quality of extracted DNA may be poorer for older specimens because of changes in the methods of sampling and fixation (28 ).
Thus, we examined 89 biopsy specimens with histological types of por2 and/or sig to examine the utility of MAb MUC1-014E for pathological diagnosis of por2 and sig in biopsy specimens, because these types are frequently seen in scirrhous gastric cancers with a very poor prognosis [ 2].
It is difficult to obtain age-matched control meniscal specimens because osteosarcoma occurs often in younger patients while OA occurs mostly in older patients.
No virus isolation was attempted on brain specimens because all were received in formalin, despite guidelines for submission of samples in glycerol saline.
Synthetic bone test specimens are often used in favour of cadaveric specimens, because of their low variance in material properties and availability (when compared to cadaveric specimens), and for the uncontaminated and clean test environment that they provide.
This conclusion was drawn by noting that the shorter specimens displayed much smaller in-plane Poisson ratios near the specimen ends compared with taller specimens (because of larger loading end-induced in-plane constraints) even though all specimens irrespective of their heights and aspect ratios accommodated the same overall axial strain.
The diagnosis of IM is currently based on the histology of biopsy specimens because IM usually appears in flat mucosa and has few morphologic changes, and identification of IM by conventional endoscopy has high interobserver variability and a poor correlation with histological findings.
This has been a significant obstacle for analysis of CD70 in pathologic specimens because most archival tissues are preserved as FFPE samples, in which existing anti-CD70 antibodies fail to work.
